What is Moissanite?

What is Moissanite?

Moissanite is one of the most brilliant gemstones on earth — and it’s not a diamond. Originally discovered in a meteor crater in 1893 by scientist Henri Moissan, moissanite is now lab-created, making it an ethical and sustainable choice for fine jewelry.

How Does Moissanite Compare to Diamond?

Moissanite actually has a higher refractive index than diamond, meaning it produces more fire and brilliance — that rainbow sparkle you see in the light. Here’s a quick comparison:

  • Hardness: Moissanite scores 9.25 on the Mohs scale (diamond is 10) — making it extremely durable for everyday wear
  • Brilliance: Higher refractive index than diamond — more sparkle, more fire
  • Color: Our stones are D Color (colorless) — the highest grade
  • Clarity: VVS1 — virtually flawless to the naked eye
  • Ethics: 100% lab-created — no mining, no conflict
  • Price: A fraction of the cost of a comparable diamond
